Submission

Week 12, Sunday 16 October 2022

Group 1(9 Marks, 3 Marks for each question)

Question 1. In your own words, explain why packet-switched networks are used for data communication instead of Circuit switched(200-250 words).

Question 2. Discuss the importance of following protocols(100 words each).

1. TCP
2. BGP
3. OSPF

Question 3. In a short paragraph(200-250 Words), explain DNS and DHCP and why they are important.

Group 2(16 Marks, 4 Marks for each question)

In this activity, you are given the network address of 205.10.0.0/18 to subnet and provide the IP address for the network shown in the topology. Each LAN in the network requires enough IP addresses for end devices, the switch, and the router. The connection between Branch 1 and Branch 2 will require an IP address for each end of the link (You can ignore this connection).

You will subnet the network address 205.10.0.0/18. The network has the following requirements:

• Sw0 LAN will require 8000 host IP addresses (Subnet 0)
• Sw1 LAN will require 4000 host IP addresses (Subnet 1)

• Sw2 LAN will require 2000 host IP addresses (Subnet 2)
• Sw3 LAN will require 1000 host IP addresses (Subnet 3)

1.  Determine the following information for Subnet 0 (4 Marks).

1. Calculate the Network IP for subnet 0.
   1. Calculate the Subnet Mask for subnet 0.
   1. Calculate the Broadcast IP for subnet 0.
   1. How many usable host addresses will this subnet support?

2.  Determine the following information for subnet 1 (4 Marks).

1. Calculate the Network IP for subnet 1.
   1. Calculate the Subnet Mask for subnet 1.
   1. Calculate the Broadcast IP for subnet 1.
   1. How many usable host addresses will this subnet support?

3.  Determine the following information for subnet 2 (4 Marks).

1. Calculate the Network IP for subnet 2.
   1. Calculate the Subnet Mask for subnet 2.
   1. Calculate the Broadcast IP for subnet 2.
   1. How many usable host addresses will this subnet support?

4.  Determine the following information for subnet 3 (4 Marks).

1. Calculate the Network IP for subnet 3.
   1. Calculate the Subnet Mask for subnet 3.
   1. Calculate the Broadcast IP for subnet 3.
   1. How many usable host addresses will this subnet support?
